Pointers for Dealing with, Storing, and Transporting Frozen Concrete Mixtures or Freshly Positioned Concrete
ACI 306.1 gives pointers for dealing with, storing, and transporting frozen concrete mixtures or freshly positioned concrete to forestall injury as a consequence of chilly temperatures.
- Frozen concrete mixtures ought to be saved in a sheltered space protected against wind and frost.
- Freshly positioned concrete ought to be coated with a water-resistant membrane throughout transportation and storage.
- Concrete shouldn’t be transported on a flatbed truck if the temperature is under 40°F (4°C).
Really useful Concrete Temperatures, Wind Speeds, and Air Frost Temperatures for Varied Zones
ACI 306.1 recommends the next temperature ranges, wind speeds, and air frost temperatures for numerous zones to forestall injury as a consequence of chilly climate:
| Zone | Wind Pace (mph) | Concrete Temperature (°F) | Air Frost Temperature (°F) |
|---|---|---|---|
| Zone 1: Temperate | 0-10 | 25-50 | 25 |
| Zone 2: Chilly | 10-20 | 15-30 | 15 |
| Zone 3: Very Chilly | 20-30 | 0-15 | 0 |
| Zone 4: Extraordinarily Chilly | 30-40 | -10 to 0 | -10 |
